Dear community, I am facing a weird problem on using the SPI after migrating my codes from STM32F407 to STM32F767.The SPI is configured as slave and interfaces with another STM32F406 MCU as master. The data received by the slave is sometimes shifted ...
I have sent a request to download the Library hand have gotten the validation and download link, however, the "Get Software" button is showing "Validating" button instead.
I am trying to implement a star SPI interface, using STM32F4 as a single master, and interfaces with multiple STM32F4 MCU using SW managed NSS. I have made sure that SSI is cleared when NSS is activated and set when NSS is deactivated so that the SCK...
Posted on March 16, 2018 at 22:20Hi Community,On a STM32F407 MCU, I wish to generate a single pulse with TIM4 PWM when triggered by ADC watchdog interrupt, with least delay possible.Taken from the reference manual RM0090 One-pulse Mode section, ...
Posted on March 15, 2018 at 15:35Hi all,I am about the configure the timer frequency which will trigger ADC to continuously scan and convert 5 channels. The callback will be from DMA.The MCU I am using is STM32F407. System core clock is 168 Mhz. Fpc...
Faced the same issue and managed to find the solution.The problem is especially pronounced if you are using the init codes from HAL to initialise the RTC, because it basically skips updating the RTC_CR register in every init call after rebooting onc...
Hi,In my application the data size, and the DMA alignments have the same size.Also have just found out in the RM, under the title "CRC Transfer Managed by DMA", the following interesting lines:The counter for the SPI transmission DMA channel has to b...
Hi Jan,Thanks for the useful tip. I have been digging in and found out that having the CRC calculation enabled was the main problem. It is weird that the DMA copies the CRC into my receive buffer sometimes and not always, causing the whole data align...
Hi,Yes I got the validation confirmation email from ST that sent me the download link, and that was how I was stuck with the Validating button.But, an hour after posting on the community I am able to download.Thanks
Hi JW,Thanks for the tip and I tried to change the slaves' NSS to be HW managed, and having them triggering EXTI as well. It now works as expected. Indeed I was misled by MXCube.So I would like to:Second the statement that having NSS HW managed may h...
